【摘要】：為解決高海拔地區(qū)低壓和低氧環(huán)境帶來的隧道施工供氧、通風等技術難題,采用現場試驗及測試的方法,對高海拔隧道施工人員缺氧狀況、供氧效果、機械排污量等進行研究,結合理論推導及數值計算,得到如下結果:人體的缺氧危險等級分為嚴重缺氧(Ⅰ)、缺氧(Ⅱ)、存在缺氧危險(Ⅲ)和不缺氧(Ⅳ)4級;基于肺泡氧分壓與氧氣體積分數關系的不同缺氧等級下的氧氣體積分數控制標準;不同海拔CO體積分數控制標準模型;基于風管開口處流量理論的風管漏風率海拔修正系數計算公式;風機風壓、功率的海拔修正系數公式;考慮人體勞動的平均能量代謝率海拔修正系數的不同海拔下施工人員勞動強度指數及強度等級。
[Abstract]:In order to solve the technical problems in tunnel construction such as oxygen supply and ventilation caused by low pressure and low oxygen environment in high altitude area, the hypoxia condition, oxygen supply effect and mechanical sewage discharge of tunnel workers at high altitude were studied by field test and test method.In combination with theoretical derivation and numerical calculation, the following results were obtained: the human body was classified into four levels of severe hypoxia (鈪，
